History of Smokejack Clay Pit

Smokejack Clay Pit is a geological Site of Special Scientific Interest located in Surrey, England. The site is a 56-hectare area that exposes Lower Cretaceous rocks of the Weald Clay Group. The pit has been studied since 1983, and fossils of six orders of insects have been discovered there.

The name “Smokejack” is derived from the brickworks that used to operate in the area. The brickworks were established in the 19th century and were in operation until the 1970s. The clay extracted from the pit was used to produce high-quality bricks that were in demand throughout the region.

The site was designated as a Site of Special Scientific Interest in 1985 due to its geological importance. The Weald Clay Group exposed at the site is of great interest to geologists and paleontologists, as it contains numerous fossils of plants and animals from the early Cretaceous period. The site is also a Geological Conservation Review site, which means that it is of national importance for its geological features.

Today, the Smokejack Clay Pit is a popular destination for fossil hunters and geology enthusiasts. The pit is open to the public and visitors can explore the exposed rock faces to search for fossils. The site is also home to a variety of wildlife, including rare species of birds and insects.

Geology and Composition

Clay Types

Smokejack Clay Pit is a geological Site of Special Scientific Interest located east of Cranleigh in Surrey. The site exposes Lower Cretaceous rocks of the Weald Clay Group, which have been studied since 1983. The clay found at Smokejack Clay Pit is mainly composed of kaolinite, a soft white clay mineral that is used in a wide range of industrial applications such as ceramics, paper, and paint.

In addition to kaolinite, the clay at Smokejack Clay Pit also contains other minerals such as smectite, illite, and quartz. Smectite is a group of clay minerals that are known for their high water absorption capacity, while illite is a type of clay mineral that is commonly found in sedimentary rocks. Quartz is a hard mineral that is commonly used in construction materials such as concrete and asphalt.

Stratification

The clay at Smokejack Clay Pit is stratified, meaning that it is layered in a specific order. The stratification of the clay is due to the depositional environment in which it was formed. The Weald Clay Group was deposited in a shallow marine environment during the Lower Cretaceous period, approximately 125 million years ago.

The stratification of the clay at Smokejack Clay Pit can be seen in the exposed rock faces. The layers of clay are separated by thin layers of sandstone and limestone, which were deposited during periods of higher sea levels. The stratification of the clay at Smokejack Clay Pit has been studied extensively and has yielded important insights into the geological history of the area.

In conclusion, Smokejack Clay Pit is a unique geological site that offers valuable insights into the geological history of the area. The clay found at the site is mainly composed of kaolinite and is stratified, providing important information about the depositional environment in which it was formed.
